BOULDER, Colo. -- Colorado appeared in the Associated Press poll for the first time in 15 years on the heels of winning the Charleston Classic.

Check out the full rankings.

Indiana and Louisville remained No. 1 and No. 2, but previously third-ranked Kentucky dropped five spots to No. 8 after losing to Duke. The Blue Devils jumped four spots to No. 5 following the win.

The Buffs came it at No. 23 in the AP poll, the first time the program has been ranked in a major poll since earning back-to-back No. 25 rankings in the Coaches Poll during the 2005-06 season. 

In the AP poll, it is Colorado's first ranking since appearing at No. 24 in the final poll of the 1996-97 season, when Chauncey Billups led the Buffs to the second round of the NCAA tournament.

It’s the first time the Buffs have been ranked before the start of conference play in 43 years, since earning a spot in 1969, coming in at No. 20. 

Overall, it is the 32nd time the Buffs have appeared in the AP rankings. CU’s highest ranking came in 1963, coming in at No. 6.
